Quick change places never touch my car. Ever.
This happened after, in an emergency, I stopped at a Jiffy Lube on my way out of town. Half a mile down the road afterward my oil light came on. So I lost an hour because I had to go back and tell them that this time, the manager himself was going to redo it.
Since I don't have the equipment or a location to do my own I found myself a good, trustworthy mechanic (believe it or not, a woman). It's a little more expensive but the peace of mind is worth it.
